HighJackthis Log Help

Hello anyone and everyone that can help!! I keep getting redirected to the stupid xspn.com search site and that is why I am here. I have run almost every imaginable spyware detection and removal tool from Spybot to Adaware to trojan hunter and all of them found things the same and some different but anytime I reboot or just go back to the web everything goes back to being the same (xspn.com search site). Since I do not have many hairs left to pull out I figured that I would seek professional help (you guys). below is the HijackThis report. Any and all suggestions would be greatly appreciated:

Empty the TIF (Temporary Internet Files)
To do so use Control Panel > Internet Options(or right click the IE icon on the desktop and choose Properties)
Click Delete Files on the General Tab - place a check in the Delete all offline content box and then press OK

Delete all the files in (and any subfolders of) the C:\Windows\Temp\ folder
